Texwipe TX740B Medium CleanFoam® Cleanroom Swab with Long Handle (Open Cell, 100 PPI)

Texwipe TX740B is a medium-head, long-handle CleanFoam® open-cell polyurethane cleanroom swab engineered for precision cleaning, particulate pickup, and controlled solvent application in hard-to-reach areas where wipes cannot maintain stable contact. The 100 PPI open-cell polyurethane foam readily absorbs solvents and solutions and helps grab particulates, while complete thermal bond construction (no adhesive) eliminates a common contamination pathway in solvent-wet swabbing. TX740B is cleanroom processed to support low levels of nonvolatile residues (NVRs) and ionic extractables, manufactured to consistent tolerances, lot coded for traceability, and packaged in a silicone-free and amide-free bag—all aligned to contamination-control workflows in microelectronics, optics, semiconductor support, medical device, pharmaceutical, and other ISO-class controlled environments. As with all swabs, performance is process-dependent and no swab is truly “zero-lint” in every condition; the goal is low-linting behavior with disciplined technique.

Long-handle access note: TX740B is widely selected when you need reach into recessed features (seams, joints, pockets, intersecting surfaces) while keeping gloved hands away from the work zone—and you want open-cell foam absorbency for solvent delivery and residue pickup with adhesive-free construction for a cleaner baseline.

About the Manufacturer:

Texwipe (an ITW company) differentiates itself in contamination-control swabbing by treating the swab as an engineered process tool, not a commodity. For CleanFoam® swabs like TX740B, the practical differentiators are the controlled 100 PPI open-cell foam structure, thermal bonding to eliminate adhesives, cleanroom processing aimed at reducing background residues and ions, and consistent automated manufacturing tolerances that help teams standardize a repeatable cleaning method.

SOSCleanroom (SOS) supports that discipline with continuity of supply and responsive technical support so teams can keep the exact CleanFoam® long-handle swab they qualified in service—reducing substitution risk and keeping critical cleaning outcomes repeatable across operators, shifts, and sites.

TX740B Benefits:

Long-handle reach for confined geometry: Helps access seams, joints, housings, corners, and intersecting surfaces while keeping gloves away from cleaned features
Absorbency for solvent-wet steps: Open-cell foam increases solvent uptake for controlled delivery and residue pickup (technique-dependent)
Cleaner construction baseline: Thermal bonding avoids adhesive as a variable in residue and extractables control
Repeatability and traceability: Lot coding and packaging controls support investigations, trending, and standardized work instructions
Operator control: Medium head size improves coverage per pass while the internal paddle supports controlled contact and pressure

Common Applications:

Applying and removing lubricants, adhesives and other solutions in a critical clean environment
Scrubbing recessed areas
Removal of excess materials and debris
Cleaning intersecting surfaces and joints
Cleaning with compatible solutions and solvents (including IPA where compatible)
Picking up fine powders
Precision cleaning and maintenance for optics handling, microelectronics support, semiconductor tools, medical device assembly, and laboratory workflows

Best-Practice Use:

Charge to damp, not dripping: Open-cell foam can carry more solvent than operators expect. Define a damp standard so seams and crevices do not flood.
One-direction, overlapping strokes: Use straight-line passes to reduce redeposit risk; avoid circular scrubbing unless your SOP requires it.
Rotate and retire early: Once a foam face loads, it becomes a transfer tool. Rotate to a fresh face and discard before streaking begins.
Avoid re-dipping into shared solvent: Use one-way dispensing (controlled bottles, aliquots, droppers) to prevent cross-contamination and keep results repeatable.
Use lowest effective pressure: Let solvent do the chemistry and foam do the transport, especially around sensitive surfaces and precision interfaces.
Validate compatibility: Verify foam/handle compatibility against your solvent system and contact time, especially if using aggressive chemistries.

Selection Notes (TX740B Fit-to-Task)

Open-cell vs. closed-cell foam: Choose open-cell foam when absorbency and particulate pickup are priorities; consider closed-cell foam when you need tighter solvent control and less liquid hold-up. Validate to your residue, surface, and inspection criteria.
Why the long handle matters: TX740B is purpose-built for access—use it when a wipe bridges over geometry or when gloved hands introduce incidental contact risk.
Technique drives outcomes: Open-cell absorbency can lift contamination or spread it. Standardize wetting, stroke direction, and change-out triggers for repeatability.
Temperature limitation: Keep use below 350°F and confirm chemical compatibility for your specific solvent and process conditions.

ISO 14644 Operations Control CleanFoam® Long Handle Series (TX740B) Foam (open-cell polyurethane) Medium head; long rigid handle Precision Cleaning / Extended Reach / Solvent Application Lot Traceability

Texwipe TX740B Medium CleanFoam® Swab with Long Handle (Open Cell, Non-Sterile) — Extended Reach for Recesses and Tool Interfaces with Higher Solvent Capacity and Feature-Level Control

Texwipe’s TX740B Medium CleanFoam® Swab with Long Handle is a cleanroom-processed, non-sterile foam swab selected when extended reach is needed and open-cell foam capacity supports the cleaning method. The open-cell polyurethane foam head is commonly used for solvent pickup and delivery in localized cleaning, with performance depending on wetness control and chemistry compatibility. A long rigid handle helps operators reach deep ports, housings, and recessed tool interfaces while maintaining clearance from adjacent surfaces and preserving stroke discipline. Operational outcomes typically depend on defined loading (damp vs. wet), short unidirectional strokes, and rotating the head to present a clean face as loading occurs. Because open-cell foam can retain and release solvent readily, method controls often include loading limits and change-out triggers to reduce pooling, streaking, and residue carryover. For controlled or validated programs, confirm construction details, dimensions, and acceptance criteria using current manufacturer documentation and lot records.

Operations takeaway: In cleanrooms, swabs are a precision tool. The outcome depends on head material, solvent loading, stroke discipline, and single-use/change-out rules.

ISO-first context: where swabs fit in cleanroom operations control

ISO 14644-5:2025 places cleaning and handling activities under a documented Operations Control Programme (OCP). Swabs belong in that system because they directly influence localized contamination (particles, fibers, residues, and solvent carryover). Where swabs are used for precision cleaning (e.g., corners, ports, fixtures) or verification-related activities, the method should be written, trained, and repeatable: approved solvent, defined wetness, defined motion (stroke count/direction), and defined change-out triggers.

Control point: “Overworking” a swab is a common failure mode. Once the head loads, it becomes a redeposit tool. Build discard frequency into the SOP.

What this swab is designed to do (typical use cases)

Precision cleaning in recessed areas: ports, cavities, housings, and restricted tool interfaces where reach affects technique
Controlled solvent application/removal (IPA, acetone, engineered solvent per SOP) where capacity and wetting characteristics matter
Removing particulate or residue from connectors, grooves, seams, and alignment features where wiper contact is too broad
Detail cleaning where maintaining clearance from adjacent critical surfaces is part of the method requirement
Sampling/verification workflows only if applicable and permitted by your SOP

Selection note: Match the swab head material to the task: foam for solvent control and low linting, polyester for durability and precision wiping, specialty options for ESD or micro-features—then validate to your surface and chemistry.

Best-practice use (reduce residues, particles, and rework)

Control introduction: bring swabs into the cleanroom per OCP rules (outer packaging removal, staging, storage).
Control wetness: use a defined “damp” loading (not dripping). Excess solvent is a primary cause of residue streaking and pooling.
Directional strokes: use short, controlled, unidirectional strokes. Avoid scrubbing that redistributes contamination.
Rotate the head: present a clean face/edge as you move; do not keep wiping with a loaded surface.
Change-out triggers: discard when the head loads, deforms, sheds, or the solvent profile changes (drying or over-wetting).
Waste discipline: discard immediately into the designated waste stream (do not stage used swabs on benches).

Method standardization tip: If outcomes vary, lock three variables: solvent used, wetness target, and stroke count per feature.

Misuse controls & when not to use

If sterility is required: do not substitute non-sterile swabs for sterile workflows.
If you are sampling for validation: do not substitute cleaning swabs for protocol-defined sampling devices and methods.
If the chemistry is aggressive: verify compatibility of the foam construction/head bond and handle material to the solvent.
If ESD is critical: use an ESD-safe swab/handle where required and validate resistance/grounding to your program.
